Paper Size mismatch 7520 on 8.5x11

[gregalexander]

I am attempting to print checks from QuickBooks and I am getting a paper size mismatch error.  The checks are 8.1x11.  If I attempt ot print the checks to my plain paper instead of loading the check stock, they will print.  The only difference in the two papers is the check stock is slightly heavier.  This is a new problem as they have always previoulsy printed fine.
